PROGRAMMING:Survey and scoring of catering service quality
In business and scientific research, people often need to analyze the data and display the results in the form of histogram, which will greatly increase the intuitiveness of these data and facilitate the analysis and comparison of data. Take the customer's rating of catering service as an example, input a positive integer repeat (0 < repeat < 10) and perform the following operations:
Enter a positive integer n (1 ≤ n ≤ 20), which means that n students are invited to score the food and service quality of the cafeteria. The score is divided into 5 grades (1 is the lowest score, 5 is the highest score). Try to count the survey results, and print out the histogram of the statistical results in the following form with *.
